我正在使用donReach.com在github项目中提供的总份额计数PHP脚本。
问题 - 除facebook外，其他所有计数服务都很完美。它总是显示0个计数。
但是，如果我使用他们的API网址来检查我的任何网址共享https://count.donreach.com/?url=http://www.twistblogger.com/2015/04/floating-social-media-share-buttons-bar-blogger-total-share-count.html
它完美地展示了所有的计数。
所以我的问题是我的问题是什么？我使用相同的PHP脚本并按照指南上传到http://codefreak.hol.es/?url=http://www.twistblogger.com/2015/04/floating-social-media-share-buttons-bar-blogger-total-share-count.html，但它没有按预期的方式工作。

对于facebook计数，此脚本使用
"https://api.facebook.com/method/links.getStats?format=json&urls=",
但在那种情况下它甚至根本没有显示facebook计数选项然后我将https替换为http并且facebook计数开始显示但始终保持为零。我也试过用graph.facebook.com/?id=更改它，但结果是一样的。
我从未使用PHP脚本，我对PHP一无所知，但我会根据您的建议尽力而为。
请指导我。任何帮助将深表感谢。谢谢！

请参阅https://developers.facebook.com/docs/graph-api/reference/v2.3/url
要查找股票编号，您必须解决以下问题：
https://graph.facebook.com/v2.3/?id=http%3A%2F%2Fwww.imdb.com%2Ftitle%2Ftt2015381%2F
您将收到URL这样的对象：
{
"og_object": {
"id": "10150298925420108",
"description": "Directed by James Gunn. With Chris Pratt, Vin Diesel, Bradley Cooper, Zoe Saldana. A group of intergalactic criminals are forced to work together to stop a fanatical warrior from taking control of the universe.",
"title": "Guardians of the Galaxy (2014)",
"type": "video.movie",
"updated_time": "2015-04-22T02:19:13+0000",
"url": "http://www.imdb.com/title/tt2015381/"
},
"share": {
"comment_count": 4,
"share_count": 109631
},
"id": "http://www.imdb.com/title/tt2015381/"
}
share_count字段包含您的信息。
<强> UPD
在函数getCount中，您必须改为编写
case "facebook":
$data = json_decode($data);
$count = (is_array($data) ? $data[0]->total_count : $data->total_count);
break;
类似的东西：
case "facebook":
$data = json_decode($data);
$count = (is_array($data) ? $data["share"]->share_count : $data->share->share_count);
break;
抱歉，我没有对此进行测试，因此您必须对其进行调试并找出哪种格式正确。
答案 1 :(得分：0)
如果您在Facebook中有应用程序，它非常简单，无需登录，您可以获取facebook计数器。
尝试一下：
https://graph.facebook.com/?id={URL}&fields=engagement&access_token={your-app_id}|{your-app_secret}
响应将类似于：
{
"engagement": {
"reaction_count": 36,
"comment_count": 2,
"share_count": 20,
"comment_plugin_count": 3
},
"id": "https://www.example.com"
}
